Who is at highest risk for getting chickenpox?

Updated July 30, 2023


Chickenpox is highly contagious and can be easily transmitted through contact with the chickenpox rash or respiratory secretions spread through the air by sneezing or coughing. Persons who are considered to be at higher risk for infection include:

  • persons who have not had chickenpox or the vaccine
  • individuals who attend or work in a day-care or school setting
  • persons who reside with children

Individuals previously vaccinated with the chickenpox vaccine may still develop chickenpox, however, the infection may be milder.  Most people who get chickenpox develop lifelong immunity, however, while rare, it is possible to have the infection more than once.  Individuals who lack immunity to chickenpox can also develop the illness by coming into contact with a shingles rash. 

IMPORTANT NOTE: NVIC encourages you to become fully informed about Chickenpox and the Chickenpox vaccine by reading all sections in the Table of Contents , which contain many links and resources such as the manufacturer product information inserts, and to speak with one or more trusted health care professionals before making a vaccination decision for yourself or your child.
